Hitachi ZH200-5A hybrid excavator with better and better
Recently, Hitachi ZH200-5A hybrid hydraulic excavator market officially for Chinese. The layout of the product line, Hitachi once again to domestic users to prove their strong R & D strength, at the same time, in the Japanese domestic market early after a large number of users, Hitachi ZH200-5A get the terminal users.
Hitachi 5A series excavator has completed the ZX55USR to the ZX890LCH models of the comprehensive upgrade, the ZH200-5A hybrid models launched more to enhance customer value experience.
Advanced hybrid technology
A new generation of ZH200-5A hybrid excavator set comprehensive technical strength of Hitachi group, the new TRIAS-HX system (hybrid system with 3 energy saving pump hydraulic system) inherits the Hitachi construction machinery in the hydraulic excavator, electric excavator, excavator etc. batterydrives product development experience perennial technology, through integration, lower realized fuel consumption and less emissions. Among them, the hybrid system will produce rotary deceleration energy through the rotary electric motor is converted to electrical energy stored in the capacitor via the PCU power controller unit, the accumulation of energy will be used as the auxiliary power rotary acceleration and the engine driver, through the effective use of the power, fuel consumption reduction achieved. At the same time, Hitachi launched the 3 machine 3 pump energy-saving control valve hydraulic system.
PCU ZH200-5A inverter used with excellent performance in the new route and the dump truck on the Hitachi inverter technology, Department of electric rotary electric motors, capacitors, power cables and other products are Hitachi manufacturing technology. In addition, Hitachi built machine follows the moving arm regeneration system and mining growth system of hydraulic excavator on the highly acclaimed.
After Hitachi construction machinery technicians test, ZH200-5A hybrid excavator in PWR mode, fuel consumption decreased 15%, fuel efficiency increased by 18% (compared with ZX200-5A); if compared with ZX200-5G, the fuel consumption is reduced 25%, fuel efficiency increased by 33%.
Achieving excellent operational performance
Learned from the ZH200-5A hybrid excavator product data, the machine is equipped with imported Isuzu ISUZU engine (4 stroke, water cooled, electronically controlled direct injection), rated power (net) reached 113kW, with 3 pump 3 valve hydraulic system, to achieve the basic performance. Not only to strengthen the design of the core components, but also optimize the fuel circuit, coupled with multi-stage fuel filtration system, so that the engine to play a good performance. The advanced cooling system ensures that the engine is in good condition, the expansion tank improves the exhaust performance of the cooling circuit, and the engine is surrounded by a high durability material, which can keep the cooling performance for a long time.
It is understood that the ZH200-5A hybrid excavator weight 20900kg standard 0.91m3 high durability and large capacity to strengthen the track plate three rib type bucket and 600mm, combined with efficient hydraulic system, has brought a large amount of work, discharge site shows its efficiency in loading. The contact surface of the bucket rod and bucket connecting parts using WC (tungsten carbide) dissolve shot, helps to reduce the wear and seizure, the maximum digging force is 158kN the bucket, the bucket rod maximum digging force is 114kN, walking speed (high / low) 5.5/3.5 (km/h).
In the condition of high strength and complex working conditions, the D platform of ZH200-5A hybrid excavator is used to effectively resist the impact of the outside. The X beam adopts an integrated welding structure, which improves the strength and stability of the car, and improves the durability. The tensioning mechanism of the tensioning wheel adopts an integrated design, which can effectively prevent the sliding of the tensioning wheel.
Comfortable operation
For operators, how to operate comfortably and safely, the degree of humanized design is crucial. ZH200-5A hybrid excavator provides ample operating space, convenient access to the driver's cab, ample foot space, wider vision of the front window. The monitor switch and the air conditioner switch are centrally arranged on the right console, and the operation is simpler. The standard suspension seat provides excellent vibration reduction effect, and adopts hydraulic elastic support to absorb shock and vibration, so as to improve the comfort of operation and reduce the fatigue of operators. A new type of slide rail is adopted to effectively reduce the clamping phenomenon caused by the sliding of the seat. The neutral engine starting system can prevent the operator from going wrong when the machine goes up and down, and avoid the risk.
